Inflation in uplifted supergravities
Inflation in uplifted supergravities
We present a model of slow roll inflation in the context of effective supergravities arising from string theories. The uplifting of the potential (to generate de Sitter or Minkowski vacua) is provided by the D-term associated with an anomalous U(1), in a fully consistent and gauge invariant formulation. We develop a minimal working model which incorporates eternal topological inflation and complies with observational constraints, avoiding the usual obstacles to implementing successful inflation (the ? problem and the initial condition problem among others).

Abstract
We present a model of slow roll inflation in the context of effective supergravities arising from string theories. The uplifting of the potential (to generate de Sitter or Minkowski vacua) is provided by the D-term associated with an anomalous U(1), in a fully consistent and gauge invariant formulation. We develop a minimal working model which incorporates eternal topological inflation and complies with observational constraints, avoiding the usual obstacles to implementing successful inflation (the ? problem and the initial condition problem among others).
